DISCHARGE OUTLET.

Application filed July 14,

Reference is had to the accompanying drawings which illustrate thepreferred form of the invention; though it is to be understood that theinvention is not limited to the exact details of construction shown anddescribed, as it is obvious that various modifications thereof withinthe scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is a sectional view of the discharge outlet of the presentinvention, showing the same attached to a. tank; and

Fig. 2 is a sectional view on the line 22 of Fig. 1, showing a portionof the gasket removed.

This invention relates to discharge outlets for tanks, and hasparticular reference to a discharge outlet which may be heated tofacilitate the discharge of the tank lading.

The primary object of this invention is the provision of a dischargeoutlet for tanks comprising a jacketed casing formed of separable parts,the'parts defining a heating space therebetween.

Another object of the invention is the provision of a discharge outletfor tanks hav ing a nozzle and a removable or replaceable jacketdefining between the discharge nozzle and jacket, a space or chamber forreceiving a heating medium.

A further object of the invention is the provision of a heated dischargeoutlet for tanks which is easy and inexpensive to manufacture, strongand durable in use, and which consists of few parts.

Other objects and advantages of this invention will be apparent from thefollowing description taken in conjunction with the accompanyingdrawings, in which 1 indicates the bottom of a tank having a dischargeopening 2 formed therein. The discharge outlet of the present inventionincludes a nozzle indicated generally at 4; which is preferably a hollowcasting having a threaded opening 5 in the upper end thereof forreceiving a valve seat, not shown, and also having a lateral attachingflange 6 to take the rivets 8 by which the nozzle is secured to thetank.

192?. Serial No. 205,799.

As clearly shown in the drawings, the flange 6 is wider at one portionto provide a surface through which a steam pipe 10 extends, but this ismerely by wayof example as the opening formed inthe'flange may be closedby a suitable plug when it is not desired to pass the steam into thetank, or the flange may be entirely free of such opening, if desired. I

The lower portion of the nozzle is provided with a machined surface 12just above the end 11, and said end is internally threaded as shown at14 to receive a hose connection, not shown. g

The body of the nozzle tapers downwardly for aportion thereof, asillustrated at 16., from a circumferential machined portion 18 adjacentthe flange 6, and below said tapered portion the body of the nozzlestraight as shown at 20, the lower end of this straight portion mergingwith the end 11 at the thickened portion 22, the external surface ofwhich is machined as at 12, as heretofore I mentioned. I

The outlet of the present invention also comprises an independent jacket24: having an inlet opening in which is secured an inlet pipe 26 leadingto the space between said jacket and nozzle. As clearly shown in thedrawings, the jacket is provided with upper and lower flanges 23 and 25,the face of each of which is machined as shown at 28 and 30respectively,-which surfaces, when the jacket is positioned on thenozzle, contact with the before-mentioned machined portions or surfaces18 and 12 respectively.

One portion of the upper flange of the jacket is considerably wider thanthe remaining portion, defining a web 27 having the openings 29 formedtherein, and said flange is preferably reinforced at this portion of thejacket by means of the ribs 31. It will be ap parent that the reason forwidening the jacket at this point is to provide communication betweenthe space formed by the jacket and nozzle and the steam pipe '10heretofore described.

Adjacent the lower end of the jacket and substantially opposite theinlet pipe 26 is a discharge opening which, in the instance shown, isclosed by a removable plug 32 but which may have a steam pipe connectedthereto in lieu of the plug, if desired.

The jacket, as before-mentioned, is independent of the nozzle 4 and isreadily removable therefrom. The upper and lower ends of the jacket areeach provided with a circumferential groove in which is seated a packing34 which may be a lead packing or a suitable gasket. The jacket isinserted over the nozzle with the respectivemachined portions in contactwith each other, and said jacket is retained in its position on thenozzle by means of a nut 36 which threadedly engages the externalthreads 38 of the end 11 of the nozzle. Itiwillbe apparent that uponscrewing the nut a close fit of the acket with the flange 6 is obtained,and a substantially leak proof connection is established between theseveral parts of the invention.

In use, a heating medium is passed from the inlet pipe 26 into the space40 formed between the nozzle and the jacket and, in the instance shown,the steam is directed through the pipe into suitable heating coils, not

shown, arranged within the tank, and from such heating coils the steamis directed from the tank in any suitable manner. As heretoforespecified, a discharge pipe may be secured in lieu of the plug 32 inwhich event a portion of the steam in the space 40 will be led throughthe pipe 10 into the tank and the remaining portion may be led from thespace 40 through an outlet pipe employed in lieu of the plug 32.

The invention shown and just described is extremely simple, and it willbe obvious that should the jacket 24 become broken or distorted, thedischarge outlet may be readily repaired by merely backing off the nut36,

removing the distorted jacket and replacing the same with a new jacket,securely held by the nut 36. p

What is claimed is:

1. In combination with a discharge nozzle having a threaded lower end, acaslng surrounding the nozzle and removable therefrom and definingachamber for receiving a heatmg medium, and means secured to the threadedlower end of thenozzle for securing the casing in position. I

2. A dischargeoutlet for tanks comprising a nozzle, a casing surroundingsaid nozzle in spaced relation thereto to define a chamber for receivinga heating medium, and means secured to the lower end of the nozzle forsecuring the casing in close fitting engagement with the nozzle.

.3. A discharge outlet for tanks comprising a nozzle having a lateralattaching flange at its upper end, a casing surrounding the nozzle inspaced relation thereto and defining a chamber for receiving a heatingmedium, and

means engaging the lower end of the nozzle for maintaining the casing inclose engage,-

ment with the nozzle and the attaching flange.

4. In combination with a discharge nozzle, a casing surrounding thenozzle intermediate the ends thereof and removable therefrom, meansformed on the casing for retaining the same in spaced relation to thenozzle to define a heating space therebetween, and means removablysecured to the lower end of the nozzle for retaining the casing on thenozzle.

5. In combination with a discharge nozzle having a threaded lower end, acasing surrounding the nozzle and freely removable therefrom, inwardlyextending portions at each end of the casing for positioning said casingin spaced relation to the nozzle, apart of one of said inwardlyextending portions defining an apertured web, and means secured to thelower end of'the nozzle for retaining the casing in position on thenozzle.

6. A discharge outlet for tanks comprising a nozzle having an attachingflange at its upper end and spaced circumferential machined portionsintermediate its ends, a removable casing surrounding said nozzle andprovided with machined portions adapted to contact with the beforementioned machined portions to position the casing in spaced relation tothe nozzle, and means engaging the lower end of the nozzle for retainingthe casing in position on the nozzle.
